Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an accumulating device suitably used in a product packaging device, and more specifically, in a pre-process of a final packaging process, a plurality of odd-shaped products are arranged in a fixed pattern. The present invention relates to an integrated device.

The finished product that has undergone a manufacturing process is generally transferred to the packaging process, where it is packaged in an appropriate shape and size, taking into consideration convenience in transportation, storage, and handling, as well as visual aesthetics. In this case, as a pre-process to the final packaging process, an accumulation device is used to arrange a plurality of products in a certain pattern. By the way, the shapes of products that can be stacked by this stacking device are mostly limited to rectangular parallelepipeds and cylinders, and stacking irregularly shaped products with other external shapes requires an extremely crude mechanism. Currently, rational integrated packaging for these types of odd-shaped products is lagging behind, as it relies heavily on manual labor. In many cases, it is difficult to arrange a plurality of irregularly shaped products in a predetermined pattern so that they can be packaged in boxes or the like with good space efficiency. However, even if the product has an external appearance other than a rectangular parallelepiped or cylinder, for example, a product consisting of a column whose cross section is T-shaped, triangular, trapezoidal, or hook-shaped. By inverting one product and arranging it adjacent to the other product, it is possible to accumulate the products in a uniform volume with a small external shape. Irregular-shaped products that stably have the minimum external volume when placed adjacent to each other,
The present invention relates to a device for efficient integration.

For example, T-shaped handy razors are generally sold in packs of 5, but such odd-shaped products are packaged in boxes that are most space-efficient for convenience in transportation and storage. In this case, it is conceivable to turn the products upside down and arrange them next to each other as shown in FIGS. 1a and 1h. When aligning and stacking products in a pattern in which one product is placed upside down and adjacent to the other, as mentioned above, in the previous process, five T-type handy razors are used in one batch. After that, they are sequentially conveyed on a conveyor toward a collection device, but if we closely observe this conveyance and supply form, they can be classified into the following cases.

In other words, ■ When the T-shaped colored bodies are conveyed on the conveyor in a stable inverted position with their heads facing down and are fed in close contact with each other as shown in FIG. 2a, ■ As shown in Figure 2b, a predetermined narrow gap is provided between adjacent T-shaped packaging bodies. As shown in Figure 3a, the T-shaped colored packaging bodies are in close contact with each other, When the package is supplied at the level of tiers, ■ As shown in Figure 3b, a predetermined narrow gap is provided between each T-shaped package, and when it is supplied at the level of two upper and lower tiers, ■ 4a As shown in the figure, the packages fed at the lower level have their heads down, the packages fed at the upper level have their heads up, and the packages are in close contact with each other. (2) Based on the feeding form shown in FIG. 4a, 12, however, a predetermined narrow gap is provided between each package.The feeding forms shown in FIG.

Since the basic mechanism of the stacking device for odd-shaped products according to the present invention also differs according to the difference in the supply form of the products conveyed to the stacking device w as described above, it is necessary to consider each supply mode separately. First, as shown in the previous figure, one product is placed upside down and adjacent to the other in an immediate stacking pattern, and as shown in Figure 1b, a predetermined space is placed between irregularly shaped products A, B, and C. Generally, one gap is provided, and an inverted and reversed irregularly shaped product, E, is interposed in this gap. Therefore, as shown in Fig. 2b, when the irregular-shaped products are transported with a predetermined gap g between them, the irregular-shaped products A, B, and C are stacked against each other, and the irregular-shaped products E are placed upside down. Then, the lees may be collected as shown in FIG. 1b.

Furthermore, when the products are supplied in two levels, upper and lower, as shown in FIG. 3b, the same is true in that a means for turning the irregularly shaped products E in the upper stage upside down is required.

Therefore, the apparatus for accumulating irregularly shaped products according to the present invention includes a plurality of suction holding means for holding a part of a plurality of irregularly shaped products for each individual product, and a plurality of suction holding means for holding a part of the irregularly shaped products for each product, and a 180
The apparatus is characterized in that it comprises a rotary suction holding means that rotates to turn the odd-shaped product upside down, and an elevating drive means that raises and lowers the suction holding means of the number.

9- In this case, it is preferable that each of the plurality of suction and holding means and the rotary suction and holding means be provided with a vacuum chamber, and that the suction and holding of the irregularly shaped product be performed by vacuum suction.

In addition, the rotation suction holding means is a combination of a swinging pneumatic motor and a speed reduction mechanism connected to the motor, and an Amatake electric motor 4''
It is configured to rotate forward and reverse by the combination of the electromagnetic pull clutch and the electromagnetic pull clutch.

Furthermore, it is preferable that the lifting/lowering driving means is constituted by a pneumatic cylinder in which a support plate on which a plurality of suction holding means are arranged is connected to the tip of the binutonrondo. During rotation, the rotation is stopped at a predetermined angle by a stopper driven by a pneumatic cylinder.

By the way, irregularly shaped products that are packaged in one bank in the pre-processing process leading to the stacking device are packed in multiple rows and strips in a so-called "pressed state" (because they are often fed IL), as shown in Figure 2a. , At this time, in addition to the reversing means of DP irregularly shaped product,
In the accumulation process, a means is required to provide a predetermined gap g to the group of supplied products. Similarly, when the products are supplied in close contact with each other at the upper and lower levels as shown in Figure 3a, the irregularly shaped products are
Reversing means of E and irregularly shaped products A and B that are in close contact with each other
, C is required to provide a predetermined gap g between them. In this case, the dimension of the gap 1g is set to be equal to or slightly larger than the dimension G of the irregular-shaped products located in this gap after stacking. Therefore, another irregular-shaped product stacking device according to the present invention a plurality of suction holding means for holding a part of the irregularly shaped products separately for each product;
a rotary suction holding means that rotates by 80 degrees and turns the odd-shaped product upside down; a means for opening the plurality of suction holding means mutually to provide a predetermined gap between the odd-shaped products; and a plurality of suction holding means It is characterized in that it is separated from the elevating drive means for elevating and lowering the means.

In this case, the means for providing a predetermined gap between the deformed products is
It is preferable that the suction and holding means for the number of plates be configured as i~ by interposing a compression coil spring between adjacent suction and holding means via a sliding member.

It is still necessary to provide means for applying a predetermined distance Rg between irregularly shaped products A, B, and C at the lower level, as shown in FIG. 4a.

Accordingly, yet another stacking device for odd-shaped products according to the present invention includes a plurality of first suction holding means for holding a portion of a plurality of odd-shaped products separately for each product, and a plurality of first suction holding means located above the first suction holding means, A second suction/holding means for holding the remainder of the odd-shaped product in an inverted state, and a means for separating the plurality of first suction/holding means from each other to provide a predetermined gap between the odd-shaped products. It is characterized by 5 things.

Furthermore, when taking the supply form shown in FIG. 4b, the irregularly shaped products E on the upper level are replaced with irregularly shaped products A and E on the lower level.
A means to hold it toward B and C is required.

Therefore, if there is a device for collecting irregularly shaped products according to another invention of the present application,
a plurality of first suction/holding means for holding a portion of a plurality of irregularly shaped products for each individual product; and a second suction/holding means located above the first suction/holding means for holding the remainder of the irregularly shaped products in an inverted state. It is characterized by comprising an adsorption holding means.

Next, the apparatus for accumulating irregularly shaped products according to the present invention will be described in detail below with reference to the accompanying drawings, citing preferred embodiments. As a preferred embodiment, the supply form shown in FIG. An accumulation device will be described in which the abutted irregular products are fed at the same level in a stable head-down position. The illustrated embodiment also includes:
This example was obtained by arbitrarily selecting a preferred example from among many embodiments of the present invention, and it goes without saying that the present invention is not limited to the configuration shown in this example.

FIG. 5 to FIG. 9 show an embodiment of the device for accumulating irregularly shaped products according to the present invention, and as described above,
This device is particularly suitable for the processing of products supplied in the form shown in the figures. In FIG. 5 and FIG. 7, reference numeral 10 indicates a conveyor that connects the previous process and the accumulating device according to the present invention.I7.5 Irregular-shaped products 12, which are simply packaged with five T-shaped convenient razors, are The object is conveyed by the conveyor 10 in a stable position with the head facing down. In this embodiment, as shown in FIG. 2a, the irregularly shaped products 12 are constructed as one block of five rows and five strips, and are intermittently fed on a conveyor 10 toward a stacking device.

At the same horizontal level as the conveyor 10, the accumulating device according to the present invention includes three suction holding plates 14 and one rotating suction holding plate 16 in order from the end side of the conveyor 10 in the product feeding direction. As shown in FIG. 7 and FIG.
It has 8. This vacuum chamber 18 includes three vacuum chambers 18 arranged on three suction and holding plates 14 and a rotating suction and holding plate 1.
Each section of one vacuum chamber 18 disposed in 6 is connected to an independent vacuum source (not shown). As shown in FIG. 5, the three suction and holding plates 14 are provided with small diameter suction holes 20.
An appropriate number of large-diameter suction holes 20 are formed in each rotary suction support plate 1G, and these suction holes 20 are communicated with the vacuum chamber 18. As shown in Fig. 7, rotate suction holding plate】6
, and the vacuum chamber 18 of the adjoining adsorption/holding plate 14 .
It is preferable to arrange an abutment member 21 between the two.

The suction holding plate 14 (three pieces) and the rotating suction holding plate 161
゛As will be described later, the irregularly shaped products 12 are arranged in one row of five and two rows, respectively.
Since five rows are held by vacuum suction, the rotary suction holding plate 16 has an area approximately twice that of one suction holding plate 14, and a stop plate 22 is placed upright on the longitudinal edge of the rotating suction holding plate 16. ~
Then, the irregularly shaped product 12 fed onto the rotating suction holding plate 16 is stopped at a predetermined position. One side of the rotary suction holding plate 16 is connected to a rotary drive device via a rotary arm 24 as shown. That is, on the pedestal 26 disposed adjacent to the suction holding plate 14, 16, a swinging pneumatic motor that performs an angular movement of rotating 180'' and returning to the original position is installed, and a gear 32 provided on its rotation shaft 30 is installed. The rotary arm 24 is connected and fixed to the other end of the rotary shaft 36, which meshes with a gear 38 provided at one end of a rotary shaft 36 rotatably supported by a pair of bearings 34 and serves as a deceleration shaft. Therefore, in FIG. 7, if the rocking pneumatic motor 28 is rotated counterclockwise, the rotary arm A, 24 and the rotary suction holding plate 16 supported thereon are reversed 180° clockwise Z. As can be understood, the hole formed in the vacuum chamber 18 of the rotary suction holding plate 16 is a vacuum port connected to the independent vacuum source described above, and is designated by reference numeral 40.

Next, the lower support structure of the three suction and holding plates 14 will be explained. When these suction holding plates 14 are aligned with the rotating suction holding plate 16 as shown in FIG. 7, they are in close contact with the flat surface. When rotated and separated from the alignment surface, the two suction/holding plates 14, 14 are separated from each other by a predetermined distance to form a gap. That is, elongated sliding members 42a and 42b are respectively arranged on the lower surface of each prismatic vacuum chamber 18 corresponding to the two suction and holding plates 14, and at right angles to the sliding members 42. Two sliding rods 44
．． The sliding members 4.2a and 42b are inserted into the sliding rods 44, 44 so as to be slidable in the axial direction. One end of the two sliding rods 44 is fixedly supported by an L-shaped angle member 48 attached to a support plate 46 (described later) that can be raised and lowered as shown in FIGS. The end portion is fixed to a fixing member 49 provided in the vacuum chamber of the remaining suction support plate 14. Further, a board 52 is horizontally fixed to an angle support member 50 disposed inside the housing of the accumulating device, a pneumatic cylinder 54 is attached to this board 52, and the end of a piston rod 56 of the cylinder 54 is fixed to the support plate 46. The support plate 46 is configured to be able to move up and down by energizing and deenergizing the pneumatic cylinder 54. At this time,
As shown in FIG. 7, it is preferable that the base plate 52 is provided with a guide rod 58 connected to the bottom of the support plate 46 to guide the smooth upward and downward movement of the support plate 46. As can be clearly seen from FIG. 9, which shows the cross section taken along line -B, two sliding members 42a and 42b are slidably inserted and supported by the sliding rod 44°44, and a fixing member 49 disposed at the end of the rod. An appropriate number of compression coil springs 60 are interposed between the sliding members 42a and 42a.
, 42b is pressed. Note that FIG. 9 shows the B-B in a state where the rotary suction support plate 16 is aligned with the other suction support plates 14 and restrains the movement of the suction support plate 14, as shown in FIG. A line cross section is shown. Two stoppers 62 having elastic rubber pieces are fixed to the sliding member 42a, and a tubular stopper 64 extending from an elastic sleeve on the rods 44, 44 is provided between the sliding member 42b and the fixed member 49.
are inserted and fixed to provide a predetermined gap between each sliding member 42a, 42b and fixed member 49, respectively. Also rod 44
．． As shown in FIG. 9, a stopper/axe and a winter shock plate 66 made of an elastic member are attached to the outer vertical surface of the bent angle member 48 through which the sliding members 42a and 44 are inserted and supported. ,
The moving distance of 42b when it is slid open is regulated.

Furthermore, as shown in FIGS. 7 and 8, a pneumatic cylinder 68 is attached to the base plate 52 so that its central axis is slightly inclined with respect to the perpendicular line, and when the piston door 0 is extended, the rod end is positioned so that it interferes with the rotating suction support plate 16 (described later).

The operation and effects of the device for accumulating irregularly shaped products according to the present invention configured as described above are shown in FIG. 1 of the attached drawings. Oa figure to 1st
This will be explained below with reference to Figure 0e. First, in FIG. 10a, along the horizontal supply level
As shown in figure a, a block of 5 rows and 5 strips in close contact with each other is conveyed intermittently on a conveyor from the previous process, and 3
1 row of 5 strips of irregularly shaped products A and B on each suction holding plate 14
, C are placed, and at the same time, an irregularly shaped product E is placed on one rotary suction holding plate 16. In this state, each of the products 18 is connected to a true drilling source (not shown) by operating a control valve, and the irregularly shaped products A to E are firmly vacuum-suctioned and held by each of the suction and holding plates 14 and 16. In addition, at this time, the piston rod 56 of the pneumatic cylinder 54 is extended, and the suction holding plate 1.4,
16 is maintained at horizontal supply level X.

Then, when the oscillating pneumatic motor 28 is energized, the io
As shown in Fig. b, the rotating holding plate 16 is a deformed product, and E
While holding the product by suction, rotate it 180° counterclockwise to turn the product upside down. Further, due to the rotary movement of the rotary suction holding plate 16, the suction holding plate 14 which was still in contact with the rotary suction holding plate 16 is released from the pressing lock by the rotary suction holding plate 16, and is under the expansion action of the compression coil spring 60. To,
The sliding members 42a and 42b slide and expand on the flighting rod 44, and the suction holding plates 14 holding the irregularly shaped products B and C also expand, providing a gap g between the products A, B, and C. be done. This gap dimension g is regulated by the buffer plate 66. At the same time, the pneumatic cylinder 54 operates to suck and retract the piston rod 56, so that the irregularly shaped products A, B,
The holding plate 14 that has absorbed C is lowered below the horizontal supply level X. This is the irregularly shaped product C on the suction holding plate 14.
The upper extending portion of the rotating suction holding plate 16 that has started rotation L2
This is to avoid interference with the vacuum chamber 18 of.

In this way, as shown in FIG. 10c, irregularly shaped products A,
llj and C are respectively adsorbed and held on the suction holding plate 14 with a predetermined gap g between them, and the remaining irregularly shaped products are
E is attracted by the rotating suction holding plate 16 and is turned 180 degrees and faces downward. Next, the pneumatic cylinder 54 is driven to slowly raise the support plate 46 fixed to the piston rod 56, and when the original supply level X is reached, the vacuum in the vacuum chamber 18 of the rotating suction holding plate 16 located above is reduced. unlock. Then, the rotating suction holding plate 16
Irregularly shaped products E and E, which were being held in an inverted position, fell down and fell onto other oddly shaped products A and B.

C, and are accumulated with the minimum external shape as shown in FIG. 10d (in this case, the supporting plate 46 is raised above the original supply level
). At this time, the rotary suction holding plate 16 released from the vacuum is reversed under the reverse action of the swinging pneumatic motor 28 and begins to return to its original position, or the other pneumatic cylinder 68 is energized and the piston rod 7
0 is extended, and the rotation of the holding plate 160 is blocked by the piston Ron door 0 at the position of the rotary suction holding plate 16 shown by the solid line in FIG. 10d. This is because each gap g formed between the irregularly shaped products A, B, and C on the suction holding plate 14 is set slightly larger than the dimension G of the irregularly shaped product that falls and lands in this gap (see Figure 2a). As a result, the lateral dimension of the stacked products protrudes by 2 (g-G) during stacking, so the rotary suction and holding plate 16 is used to bring the stacked products into close contact with each other without any gaps. In this way, the group of irregularly shaped products accumulated in the form shown in FIG.
(not shown), the product is discharged from the adsorption/holding plate 14 and transferred to a caser such as a cartoning machine or other case for the next process.

Next, when the pneumatic cylinder 68 is actuated to move the piston door 0 backward, the rotary suction holding plate 16, which had been prevented from moving in the inclined state, starts moving again and reaches the original supply level X as shown in FIG. 10e. Return and stop. At this time, the side part of the vacuum chamber 18 of the rotary suction holding plate 16 comes into contact with the suction holding plate 14 and the contact member 21 that protrude to the right under the expansion of the coil spring 60, and further forces the coil spring 60. The sliding part blades 42a are compressed.

42b is slid onto the guiding rod 44, and the series of cycles is completed in the state shown in FIG. 10e in which the suction holding plates 14 are brought into close contact with each other, and the next supply of the irregularly shaped product is awaited.

In the embodiment shown in FIGS. 10a to 10e, a gap is not provided between E and the irregularly shaped product that is suctioned and held in an upside-down state by the rotating suction holding plate 16. However, it is clear that if the irregularly shaped products E are also provided with a gap g, the irregularly shaped products A, B, and C will accumulate more smoothly when the irregularly shaped products A, B, and C are landed. Therefore, it is preferable to provide a gap g between the irregularly shaped products and E held by the rotating suction holding plate 16, if desired. An embodiment of this means is shown in FIG. Reference numeral 100 in the figure indicates a vacuum chamber, and this vacuum chamber 1
00 is a rotary suction holding plate 104a via the suction hole 102,
104b, and one suction holding plate 104a is in communication with the other suction holding plate 104b under the action of the suppression piston 106.
It is configured to be able to slide freely against the That is, the 10th
As shown in Figure c, the irregularly shaped products E on the upper level are suctioned and held by the device shown in Figure 14, and are positioned above the irregularly shaped products A, B and C on the lower level. and,
As shown in FIG. 14, the suppression piston 106 is driven to slide the suction and holding plate 104a apart from the other suction and holding plate 104b, and after creating a deformed product and providing a predetermined gap g between them, vacuum is applied. When the vacuum of the container 100 is released, the irregularly shaped products E smoothly fall and land between the irregularly shaped products A, B, and C, and are accumulated. The mechanism shown in FIG. 14 can also be suitably used in the case of the supply form shown in FIGS. 3a and 4a, which will be described later.

As described above, according to the stacking device of the present invention, the stacking of odd-shaped products, which has been difficult to automate in the past, can be processed automatically and at high speed, which greatly contributes to improving the efficiency of stacking work and saving labor. It is something. In addition, Figures 5 to 1
The apparatus of the present invention shown in Fig. 0 is suitably used for the accumulation processing of irregularly shaped products that are conveyed and supplied in the form shown in Fig. 2a. It can also be used for the stacking process of irregularly shaped products, with only slight changes made to the reversing mechanism. For example, as shown in FIG. 11, a pair of hook-shaped grip fingers 72 are pivotally attached to a base plate 74 at their bent portions by a shaft pin 76 so as to be able to swing open and close, and rollers are attached to opposite ends of the grip fingers 72, respectively. 78 is rotatably mounted on the shaft, and this row 278.78
A mechanism in which the chevron-shaped suppressing member 80 faces freely up and down is recommended. That is, the chevron-shaped pressing member 80 is fixed to the tip of a screw 25-ton rod 84 of a pneumatic cylinder 82 fixed to the base plate 74, and is elastically interposed between the grip fingers 72 and 72 when the piston rod 84 is retracted. Under the tension of the installed coil spring 86, the profiled product E is clamped by the grip fingers 72, 72, and when the piston rod 84 is extended, the chevron-shaped pressing member 8
0 is force-fitted between the rollers 78, 78, the grip fingers 72 and 72 open to release the irregularly shaped product and release E. Since this base plate 74 is configured to be reversed by 180 degrees by appropriate means, the 11th
In the state shown in the figure, the irregularly shaped product is held, E is held and brought to the accumulating device, where it is turned 180° and then the irregularly shaped product is assembled.
The sequence program may be set to release E.

In addition, in the illustrated embodiment, sliding members 42a and 42b are provided below the suction holding lever 14 as a means for providing a predetermined gap between a plurality of irregularly shaped products that are conveyed in close contact with each other.
Although the method of elastically interposing the compression coil spring 60 between the fixing member 496 and the fixing member 496 has been adopted, other mechanisms shown in FIGS. FIG. 12a shows a pneumatic cylinder 88 as a sliding drive source, and its piston rod 90.
The vacuum chambers 1.8a and 18 of the suction and holding plates 14a and 14b
The suction holding plates 14a and 14b slide in response to the forward and backward movements of the piston rod 90. Further, in FIG. 12b, an electric motor 92 (not shown, but equipped with a deceleration mechanism) is used as a drive source, and a ball screw 94 is rotated to move the suction holding plates 14a and 14b along the kite member (not shown). It moves forward and backward.

Furthermore, as a means for rotating the rotary suction holding plate 16, in this embodiment, a combination of a swing pneumatic motor 28 and a speed reduction mechanism is used as shown in FIG. 5, but an electric motor 96 as shown in FIG. is used as a rotational drive source, and by performing forward and reverse rotation through the City 1 magnetic double clutch/brake 98,
The suction holding plate 16 may be rotated and reversed.

Next, as shown in Fig. 2b, a mechanism in which the irregularly shaped products are supplied with a predetermined gap g between them is changed from the arrangement ↑W of the embodiment shown in Figs. 5 to 10. Since it is unnecessary, it can be simplified. Further, even if the rollers are supplied in two stages, upper and lower, as shown in FIG. 3b, it can be used by simply making some changes to the reversing mechanism. Furthermore, if the products are supplied at two levels, upper and lower, as shown in FIG. The above-mentioned sliding separation means for the suction holding plate is necessary to provide this. In addition, in order to transport the irregularly shaped product E on the upper level in Figure 4a, it is sufficient to use a vacuum source to attract and hold the irregularly shaped product, as shown in Figure 4b. When the products are supplied at two levels, upper and lower, the reversing means of the irregularly shaped products A, B, and C on the upper level are also provided with suction means to provide a predetermined gap between the irregularly shaped products A, B, and C on the lower level. The sliding release means for the protection unit will also be required.

As described above, according to the accumulation device of the present invention, it is possible to accumulate odd-shaped products that have a stable minimum external volume when one product is inverted with respect to the other product and placed adjacent to each other.
This can be accomplished fully automatically and extremely efficiently.

Although the apparatus for accumulating irregularly shaped products according to the present invention has been described above with reference to preferred embodiments, the present invention is not limited to the illustrated embodiments, and many improvements and improvements can be made within the spirit of the invention. Changes can be made. In addition, in the illustrated embodiment, one packaging unit of multi-bag T-shaped convenient razors is illustrated as an irregularly shaped product, but it is understood that it can be used to collect various other irregularly shaped products.
